But she did admit, after starring as seventies porn actress Linda Lovelace in a new film, she thinks the world is in the midst of a ‘sexual revolution’ – and it can’t come soon enough.

The film entitled Lovelace, in which she co-stars alongside Sharon Stone, Peter Sarsgaard and Juno Temple, depicts the porn star’s tragic life after she became a huge star after appearing in the notorious porn film 1972 Deep Throat.

The film focuses on Linda’s relationship with her husband and manager Chuck Traynor – played by Sarsgaard – who controlled her life and forced her into a career in porn.

And given that the film is about a porn star, it’s understandable to predict it will feature dozens of sex scenes.

But Amanda, aware of the taboo scenes between-the-sheets create, doesn’t understand what the problem is.

‘Sex in movies shouldn’t be as big a deal as it is,’ she told The Sun. ‘Everybody does it. Who doesn’t do it? So why are we shying away from it so much?

‘I mean I’m not flashing my everything for gratuitous reasons, I’m just exploring that on camera.

‘Guns are huge in American cinema but with sex everybody is so prim about it here. Something is changing in American cinema.’

But Amanda, 27, who starred in blockbuster Les Miserables, added: ‘We’re going through some kind of sexual revolution right now, I’d like to think.’
